The definition of a "Collector" is someone who has multiple machines, not just one that is functioning. I own a working bike, but I have no interest in collecting them. A collector is someone who could own all the Gottliebs from 1975-1980. That person actively "collects" games Working or not. A person who has one working game is an "owner".

I'd say there would be around 5000 pinball owners in Australia. Easily 10,000 games have been imported over the last 10-12 years.

I'd estimate only 200-300 would be collectors. Most collectors I know don't have an online presence.
